Environment: Delphi XE6, Windows 8.1, Excel 2013, Add-In Express Version 7.8 Release (build 1223, which is the current release).
I am updating a plug-In for Excel using Add-In Express. This is version 2, which was a major rewrite, so many things changed. I am getting two odd behaviors. Everything compiled and runs?Â?Ð??.
Odd behavior one. On exiting Excel, I get 7 AVs. Specifically exception class $C0000005 with message access violation?Â?Ð?? read of address?Â?Ð?? This issue is that this happens even though I can?Â?Ð?ét find any of my code that is running. From Delphi, I ?Â?Ð?èRun with Debugging?Â?Ð?é. This automatically starts Excel. I get the normal Excel splash screen telling me what plug-ins are being loaded. Mine is listed. The first Excel screen I see asks me what file to open. I immediately close Excel. I now get my AVs, - 7 right in a row.
Something I am running is AV?Â?Ð?éing on exit. I have basically commented out everything I can think of.
My .dpr file does NOT have any code between ?Â?Ð?èbegin?Â?Ð?é and end?Â?Ð?é.
My AddInModule only has one routine, AddInModuleStartupComplete, and the very first line is ?Â?Ð?èExit?Â?Ð?é
I have commented out all code in the ?Â?Ð?èinitization?Â?Ð?é on every form except the AddInModule, which only had only line added by Add-in Express
TadxFactory.Create(ComServer, TPaylay, CLASS_Paylay, TAddInModule);
My whole app only has FINALIZATION code in 2 places, and both only contain lines similar to
if Assigned(DM1) then
DM1.Free;
This brings me to my 2nd issue.
I tried using Madshi MadExcept. When I use that, I get a Stack overflow when I start Excel. I have increased stack size from 1 MB to 12 MB, and I still get stack overflows.
This app only runs in Excel, and AddInModule.LoadBehavior = 3; My app does not have ANY Task panes, everything is done via menu (TadxRibbonTab).
I am at a loss what to try next to debug this. I have tried viewing the AV address, and I just get assembly code. What do I do next to try to isolate where I am getting my errors?
Thanks

One additional comment, it I put break points on BOTH my FINALIZATION CODE, the order is...:
Start App
Excel Loads
I do not choose ANY spreadsheet files, but instead close Excel
AV occurs here
FINALIZATION CODE now runs.
Thanks |

Andrei,
I have started the process of stripping out my code, but it is a somewhat painful process. In the midst of this, I began to wonder if there is a conflict with other plug-ins, and I found that is the case. I am a registered user of Ablebits (Ultimate Suite for Excel, version 2015.1.0.380) , which I understand that Add-in Express develops. My code works fine without Ablebits enabled. With Ablebits enabled, when I click the Excel Close button, I get 7 AVs (but only when running from within Delphi IDE, no error messages when running Excel normally). If I am stepping through my code, the AVs BEFORE any Finalization routines in my code is executed. |
